課程概述

Have you wondered how “Things” talk to each other and the cloud? Do you understand the alternatives for conveying latency-sensitive real time data versus reliable signaling data? Building on the skills from the Sensing and Actuation course, we will explore protocols to exchange information between processors. In this course, you will learn how VoIP systems like Skype work and implement your own app for voice calls and text messages. You will start by using the Session Initiation Protocol (SIP) for session management. Next, you will learn how voice codecs such as Adaptive Multi Rate (AMR) are used in 3G networks and use them for voice traffic in your app. Learning Goals: After completing this course, you will be able to: 1. Implement session initiation, management and termination on your DragonBoard™ 410c using SIP. 2. Discover other users and exchange device capabilities. 3. Compare and contrast narrowband and wideband codecs and experience the voice quality differences between them. 4. Implement and demonstrate VoIP calls using the DragonBoard 410c....

excellent course to learn the other side of the internet of things from where it started so it's really joyful with the instructors and informative to learn with advancements with android and phone networks

Was a good course. Videos lectures could be better prepared. The Codecs were a bit complex and needed extra reference material

Course is very good!

It would be better if the lessons are more on practical side or practical quiz output

There's a lot of useful information in this course, but it's communicated in a very clear way. I suggest the teachers focus on improving the audio codecs material . This are hard concepts to graps and I feel the institute should invest in animation or multimedia production to clarify this. It's all very informative though I feel I was not able to put to practice nor to fully understand the models. A list of references to videos or some other sources would have been very useful.

For the better part, the section about setting up linphone and using Android Studio to program a little VoIP app is very clear and exciting.

The technologies taught in this course kept me updated about how the things or devices around us can communicate through each other using the Internet of Things. And the best part was to learn to build our own VoIP application and deploy it in our dragonboard. But i think that the lectures should be more descriptive about the acronyms taught . Thank You Coursera for giving oppertunity to learn the course.

Content was between shallow (everything but codecs) and deep (codecs), enthusiastic presenters but after a while the "you know" and "like" are getting really annoying.

too repetitive and too much dialogue bullshit

OK. the main professor clearly knows his stuff. On the other hand he goes into unnecessary detail and then quizzes you on it even though its not relevant to the course (typical bricks and mortar education type BS). The assistant instructors (likely this guys students) are not as great and the whole thing is amateur night.

Big difference in difficulty between the math-heavy codec theory lectures and the other material which is quite basic. Not much to do with the DragonBoard.

Module about codecs was great.

The rest was too easy. An equivalent to reading manual on internet. No value added :(.

The Course is acceptable, however, it should be called, Introduction to VoIP communication or Developing VoIP applications rather than its current title.

Assignments are either super easy or never have a right answer

Personally, I will not recommend this course for other who want to understand IoT
